終日霧雨が続く。濡れた足元と視界に注意

Niseko Hirafu's summit will experience persistent light drizzle throughout the day, with temperatures ranging from 3.6℃ to a maximum of 5.9℃. Although winds are light, the 99% humidity means your body will get wet, leading to a significant drop in perceived temperature. The base area also sees light drizzle, with a temperature difference of about 6℃ from the summit. Be prepared for colder conditions as you gain elevation.

With zero snow depth and continuous precipitation, ground conditions are entirely wet. Expect deep mud in forested areas and along stream beds, with slippery roots and exposed rocks. If venturing beyond the main Hirafu slopes towards areas like the sidecountry gates, be vigilant for slips on wet, steep terrain and rocky sections. The risk of falls on wet ground increases, especially during descent.

Recommended layering includes a quick-drying synthetic or wool base layer, a light fleece mid-layer, and a waterproof/breathable rain jacket and pants as outer layers. Carry an extra insulating layer. Crampons or microspikes are not needed, but waterproof hiking boots are essential. Don't forget gloves and a hat. While the risk of lightning and strong winds is low, continuous drizzle means visibility may be poor, so proceed cautiously. To prevent hypothermia, prioritize staying dry and warm, and keep breaks short.
